Newmont Corp. (NYSE: NEM), the world’s largest gold miner, said Monday that chief executive Tom Palmer will retire later this year, with chief operating officer Natascha Viljoen set to take over on January 1, 2026.
Palmer, who took the top job in October 2029, said it was the right time to step aside after nearly 40 years in the mining industry, including 12 with Newmont.
Viljoen joined Newmont in 2023 after leading Anglo American Platinum, now Valterra, and serving on Anglo American’s Group Management Committee.
The leadership change announcement comes on the same day Barrick Mining (TSX: ABX; NYSE: G) disclosed the sudden resignation of its CEO, Mark Bristow, who had led the Canadian miner since its 2019 merger with Randgold Resources.
The company has also undergone significant executive turnover. Earlier this year, chief financial officer Karyn Ovelmen resigned after just over two years. Long-time insider Peter Wexler was named interim CFO.
Newmont shares have more than doubled in 2025. The company recently pulled its stock from the Toronto Stock Exchange, citing low trading volumes and expected cost savings. Newmont first listed in Canada in 2019 after acquiring Goldcorp.
This month, the miner capped a year-long divestment program with the sale of its Coffee gold project in Yukon, underscoring the scale of change under Palmer’s leadership.
